A new highly contagious sub-variant of COVID-19 is spreading rapidly and has just landed on Australian shores.
What do we know about him?
The X-B-B.1.5 strain has been named as the most contagious subvariant of Omicron by the World Health Organization (WHO). The
advantages of this type refer to its high immune-avoidance properties and its ability to bind more tightly to human cells thus making them more contagious.
This transmission is also linked to the reduced ability of current vaccines to stop the spread of infection.
